British Polygraph Institute

We specialise in polygraph testing Since 1997. During the last coupe of years we have performed around 5 thousand analysis and this number rises with a rate of 250-300 annually.
As a distributor of Stoelting polygraphs, we have the newest models of polygraphs and other related devices, some of which are only beginning to enter the European market.Our examiners are fully licensed and belong to the World’s biggest and most known polygraph associations such as BEPA (British & European Polygraph Association) and APA (American Polygraph Association). We offer lie detection test in London, polygraph in Liverpool, Menchester and Leeds. Our clients are offered polygraph (lie detector) tests with the usage of the most modern device- the Stoelting CPS Pro (Computerized Polygraph System). This is the most technologically advanced polygraph, which as the only one in the world uses algorithms researched and confirmed by Utah University.
Unlike other polygraphs CPS Pro is equipped with a special sensor known as the plethysmograph enabling accurate analysis of results as also a so-called seat sensor which detects attempts of manipulating the test results by the person examined.
